Would "suicide diode" be a valid term for searching within a supplier

VTS/diode type number that is definitely made for this purpose?
No, that's my own description. Digi-Key part
SA5.0ALFCT-ND is a representative part, although not the one
I've seen in a particular power supply. (I can't find the
part number of that unit right now.)

I still cannot find specifically stated , designed to fail short
circuit in any associated datasheet for that TVS. Of course any device
might fail short or even frequently fail short but I've still never
found any TVS designed and stated as such to fail short for safety
purposes, ie as you succinctly term such a theoretical device , a
suicide device
